I think this is a good thing -- and now it looks like Logan will move to FS and start alongside last year's first round pick, SS Troy Polamalu. This is from ESPN.com:
"On March 18, they reached a three-year agreement with safety Mike Logan for more than $1 million a season. Logan had been talking to the Green Bay Packers, but his desire all along was to stay in Pittsburgh. By Logan staying, though, free safety Brent Alexander becomes expendable. A similar move was made a few weeks ago when the Steelers re-signed outside linebacker Clark Haggans. This week, the Steelers gave starting outside linebacker Jason Gildon permission to seek a trade. Something similar may happen with Alexander."To be fair, Alexander has been servicable, but he'll be 32 when the season starts and he's slow. Logan runs a 4.5 (before a couple of knee surgerys) and Polamalu runs a 4.4. I think it's time to see what a defensive backfield looks like that has speed, can stuff the run, and more importantly, can bolster the pass coverage (while it remains to be seen if Polamalu can cover effectively, I suspect he can do no worse than Alexander -- I guess the real question is, can he catch?).
